Three tough hill repeats made this a real strength-building workout, with 206 metres of climbing packed into just 7.4 km. I kept pushing the climbs, earning three achievements while closing my 700-calorie goal early in the day. My average cadence was 56 as I focused on steady power rather than speed. The effort was intense, with nearly 80% of the workout spent in Heart Rate Zones 4 and 5. Another solid step toward building stronger climbing legs and better endurance for the trails.
